Configuring Network Devices

1. A first network device, comprising: a controller processor to: receive, at the first network device, a first link layer discovery protocol (LLDP) message from a second network device communicatively coupled to the first network device, wherein the first LLDP message is received in response to the first network device determining that connection of the first network device to a management device has failed, the second network device having an active connection to the management device; extract, by the first network device, an address of the second network device; configure the first network device, by the first network device, to communicate with the second network device; send a second LLDP message to the second network device, wherein information contained in the second LLDP message is routed to the management device by the second network device, the information indicating that the network device is unable to connect to the management device; receive configuration changes from the management device via the second network device to establish a connection between the network device and the management device; and connect the first network device to the management device based on the configuration changes.

2. The first network device of claim 1 , wherein the controller processor is to listen for the first LLDP message from the second network device after a predetermined number of unsuccessful attempts to connect to the management device.

3. The first network device of claim 2 , wherein the controller processor is to identify an internet protocol (IP) address of the second network device based on the first LLDP message and to communicate with the second network device using the IP address.

4. The first network device of claim 1 , wherein the controller processor is to broadcast the second LLDP message to a plurality of network devices communicatively coupled to the first network device and wherein the plurality of network devices are communicatively coupled to the management device.

5. The first network device of claim 1 , wherein the controller processor is to implement the configuration changes at the first network device to restore connection to the management device.

6. The first network device of claim 1 , wherein the first and second LLDP messages include information about the respective network devices comprising identity, capabilities, location, and neighboring network devices.

7. The network device of claim 1 , wherein the configuration changes comprise minimum configuration changes to establish the connection to the management device.

8. The network device of claim 7 , wherein the first network device receives data packets to execute security and verification processes to determine if the first network device is a valid network device prior to receiving full configuration data.

9. The network device of claim 1 , wherein prior to receiving the configuration changes, the first network device receives a notification message from the management device via the second network device indicating an intent by the management device to reconfigure the first network device.

10. The first network device of claim 1 , wherein the address is extracted from a management type length value (TLV) of the LLDP message from the second network device.

11. A method, comprising: determining, by a first network device, that connection to a management device has failed after a predetermined number of unsuccessful attempts; listening for a first link layer discovery protocol (LLDP) message from a plurality of neighboring network devices communicatively coupled to the first network device and to the management device, the plurality of neighboring network devices having active connections to the management device; sending a second LLDP message to a second network device of the plurality of neighboring network devices, wherein information contained in the second LLDP message is routed to the management device by the second network device, the information indicating that the first network device is unable to connect to the management device via a first communication network, the second network device having an active connection to the management device using the first communication network, and wherein the first network device and the second network device are connected via a second communication network; receiving configuration changes from the management device, wherein the configuration changes are routed via the second network device using the first communication network, and the configuration changes used to establish a connection between the management device and the first device using the first communication network; and implementing the configuration changes at the first network device and establishing connection between the first network device and the management device using the first communication network.

12. The method of claim 11 , comprising establishing a communication path with the second network device based on the second LLDP message.

13. The method of claim 11 , comprising: receiving a notification from the management device via the second network device prior to receiving the configuration changes, wherein the notification indicates an intent by the management device to reconfigure the first network device; and acknowledging receipt of the notification prior to receiving the configuration changes.

14. The method of claim 11 , wherein the configuration changes include minimum configurations to restore connection to the management device, wherein the method comprises: connecting to the management device using the minimum configurations; and receiving full configurations upon execution of verification and validation processes by the management device.

15. The method of claim 11 , further comprising, prior to receiving the configuration changes, at the first network device, receiving a notification message from the management device via the second network device indicating an intent by the management device to reconfigure the first network device.

16. The method of claim 11 , wherein the first communication network is an active wireless connection and the second communication network is a wired connection.

17. A non-transitory computer-readable storage medium encoded with instructions executable by a processor of a first network device, the computer-readable storage medium comprising instructions to: listen for and receive a first link layer discovery protocol (LLDP) message from a second network device communicatively coupled to the first network device, in response to determining that connection between the first network device and a management device is unsuccessful after a predetermined number of attempts, the second network device being actively connected to the management device; extract an address of the second network device; configure the first network device to communicate with the second network device; send a second LLDP message to the second network device, wherein data contained in the second LLDP message is routed to the management device by the second network device, and wherein the data indicates that the first network device is unable to connect to the management device; receive a configuration packet from the management device via the second network device; and restore connection between the first network device and the management device based on the configuration packet.

18. The non-transitory computer-readable storage medium of claim 17 , comprising instructions to identify an internet protocol (IP) address of the second network device based on the LLDP message and to communicate with the second network device using the IP address.

19. The non-transitory computer-readable storage medium of claim 17 , wherein the second LLDP message is broadcast to a plurality of network devices including the second network device, wherein the plurality of network devices are communicatively coupled to the management device and to the first network device.

20. The non-transitory computer-readable storage medium of claim 17 , wherein the configuration packet comprises minimum configuration changes to restore the connection to the management device.
